Sap flow, wounding and compartmentalization in maple
Explains how sap flows in trees and the impact that tapping has on subsequent years’ sap flow.
Effects of Tapping Depth on Sap Volume, Sap Sugar Content, and Syrup Yield Under High Vacuum
Tapping depth strongly influences both sap yield and wounding. Numerous studies have focused on the amount of sap produced with ifferent depths, the most extensive work conducted by Morrow (1963), who found a tendency for increasing sap yields with increasing taphole depth. However, this work was conducted on gravity with 7/16” tapholes, so is less informative to most producers using 5/16” spouts and vacuum.
Factors Affecting Sap Yields from Maple Trees
Presents research on taps and tapping practices to maximize yield. Also explains sap flow and tree wounding.

Maximizing Maple Sap Yields
How to collect the most sap possible using efficient techniques.
Sap sugar within, between seasons at UVM PMRC
Changes in the amount of sugar in maple sap vary within a sap run, from day to day, throughout the season, and from year to year.
Some quick tips to achieve higher sap yield
Increasing the yield of sap from maple trees is the goal of most maple producers. While getting there isn’t a matter of one simple thing, by
following best management practices and paying attention to detail it is possible to increase sap yields, often quite dramatically. Includes links to videos.
